Jennifer Parks, 36, a kindergarten teacher from Palmdale, California, died from multiple gunshot wounds to the head.

The off-duty police officer killed at the festival, Charleston Hartfield, 34, died from a gunshot wound to the chest.

Officials have said more than 500 people were injured when Paddock, 64, a high-stakes video poker gambler, sprayed gunfire from the 32nd floor of the Mandalay Bay Hotel into a crowd of 22,000 people at the Route 91 Harvest Festival below.

When police stormed Paddock’s suite after he stopped firing, they discovered shell casings all over the floor.

“My initial scan, coming in the room with my rifle, is just seeing, I’m seeing one male down, bleeding from the face,” said Officer Matthew Donaldson. “He was not a threat. Kept going, kept going, kept going.”

Federal and local authorities have not said publicly what they think motivated Paddock to amass an arsenal of assault-style weapons and ammo.
